Alternatively, we could create mocks for {Encrypt,Sign,EncryptSign}Job. 
After all, we do not want to test encryption or signing, but just the 
correct composition of signed and/or encrypted messages. Using mocks 
will make this much simpler because they would always return the same 
values. Hence a simple string comparison of the composed messages 
against excepted result will do. With the real jobs checking a correct 
result will be more difficult because the real jobs always return 
different values (because the session key used for encryption is always 
different and signatures contain a timestamp).
